SHELL-SHAPED BODY SUITABLE FOR THE ALLOWANCE OF HIGH-IF'RESSURE STRESSES.

Application filed January 21, 1927, Serial No. 162,664, and in Germany December 4, 1923;

The device in question refers to shell shaped bodies suitable for the allowance of high, pressure stresses with the view of producing a shell shaped bodv, combined of several parts, to withstand higher pressures than the familiar shell shaped-bodies, for instance steam boilers.

For this aim my device consists out of a shell-shaped body, the sectional area of which is a combination of chambers in sector form, arranged in a multiple number in a radial sense, as will be specified and claimed later on.

' The device in question will be more readily understood by reference to the enclosed drawing, wherein represents:

Fig. 1 a sectional area of the shell shaped body;

Fig. 2 a partial cut on an enlarged scale.

Fig. 3 a partial cut on an enlarged scale,

but braced in a different way.

The body according to Fig. 1 has been constructed out of chambers, the sectional area of which show the arrangement of sectors, connected to each other which are curveshaped on the outside, with adjacent lying sides 6, arranged in a radial sense.

In the middle of the several chambers a tubular space a is left free, into which a cylindrical ring (Z of suitable sectional area has been arranged. Space 0 is made absolutely tight in order to serve as a feed or drain for the matter contained in the chambers a or as heating or refrigerating ipe.

Since the pressure in a the chambers a is equally high, the longitudinal sides I; are only under a stress of tension, arising through the pressure of the matter upon the inner and outer front plates 6 and f of the chambers 11. Asthese sides are offering a relatively small working area the body shows a high resistance against internal pressures. This resisting force even with equal plate thickness is often higher, than 4 for instance the resisting force of a single hollow-cylinder. steam boiler or of a. compre ssor-cylinder.

The recautions against the displacement of the c embers a in a radial sense are taken according'to Figs. 1 and 2 through the arrangem'ent of dove-tailed rails, which on one side are catching in corresponding grooves 71. of the inner front plates 7 of the chambers a, and on the other side in corresponding grooves i of the cylindrical ring (2.

Besides the advantage of the higher pressure-resisting-force,the ,device in question shows still the other advantage that is constructed out of a multiple number of parts, which are easily manufactured one by one and conveyed and also mounted and dismounted without the least difliculty.

What I claim'is:

1. Shell-shaped body for matter as for instance air, gases, steam and so forth under high stresses or stresses to be raised, consisting of a multiple number of chambers, each being sector shaped in cross section and arranged radially and means preventing radial displacements.

2. Shellhaped body, for matter under high stresses or stresses to be raised, consisting. of a multiple number of chambers, each being sector shaped in cross section and arranged radially, and curve-shaped on the outside. I

3. Shell-shaped body for matter under high stresses or stresses to be raised consisting of a multiple number of chambers,'each being sector shaped in cross section and arranged radially and forming a hollow space in the middle.

4. Shell-shaped body for matter under high stresses or stresses to be raised consisting of a multiple number of chambers, each being sector shaped in cross section and arranged radially and held against radially occurring displacements through dove-tailed connections.

5. Shell-shaped body for matter under high stresses or stresses to be raised con sisting of a multiple number of chambers, each being sector shaped in cross section and arranged radially and braced on a contrally located ring through dove-tailed connections.

In testimony whereof I hereunto alfix my signature.
